Would we have Shakespeare's plays if he didn't make money? Which encourages better plays: I write a play, and I can license theater companies to be able to perform it. Therefor better writers are attracted to the industry (instead of to say Ad Copywriting) and because of a higher level product, the industry thrives. I can write a passion play that the local theater will perform. I will not generate enough income to live from my product. I will not generate income from licensing my production because there is no copyright and my scripts would just get stolen/distributed freely. The industry has less quality productions. The majority of productions have no reputation of quality.
